Forwarding Yahoo mail to Gmail for IMAP access?

I really want to be able to access my Yahoo email using IMAP rather than POP. As far as I know, the only real way to do this right now is either the Yahoo web mail client, the Zimbra client, or a smartphone. I pay Yahoo for Mail Plus, so I have the ability to forward all my mail to an external address (a feature I have heard may now be free, but I have not confirmed this).

If I set up my Yahoo account to forward all messages to a Gmail account, then set up my mail client to access my Gmail, will I effectively solve my problem? Or are there other considerations (including stability, lag time, etc.) I am not taking into account.

Thanks!
